Description: We give upper bounds for sums of multiplicative characters modulo an integer q ≧ 2 with the Euler function ϕ ( n ) and with the shifted largest prime divisor P ( n ) + a of integers n ≦ x .

Description: Introduced by Kraitchik and Lehmer, an x-pseudosquare is a positive integer n ≡ I (mod 8) that is a quadratic residue for each odd prime p ≤ x, yet is not a square. We use bounds of character sums to ... More

Description: We estimate character sums over points on elliptic curves over a finite field Fq of q elements. Pseudorandom sequences can be constructed by taking linear combinations with small coefficients (for exa ... More
